1'0 all fit-hom, 1t may concern n@ a know that i. Lom ,rittmag fin- 1 cleaners4 and has for its object lthe construci tionv ota clcaneri'having mechanism and pro-A vision for its adjustment whereby it may op.- erate eitheil "as a pneumatic cleaner or a r f, i i 'ln practising'mv invention I *employ a Ahand operated pneumatic cleaner having a suction pump or bellows which is-'operat-ed b v rollers that take part ih supporting the cleaner in its movement upon the surface Ibeing cleaned and I equip such pneumatic *cleaner lwith a rotary brush and rollers adapted to turn vupon the surface over which Vthe cleaneris moving when such brush lis to operate. This brushra'ndfitsoperating rollers are 'desir-ably interposedA between the nozzle at the forward end of the pneumatic cleaner and the suction pump operating rollers loc-ated at the rear of Vthe pneumatic cleaner. lvleans are providedwhereby either .the brush'operating: rollers -orV the nozzle may alone bear upon the` surface being Acleaned so that the. device will operate either iforming no wot-l; 'as thelsuction nozzle'l through which it drawsair is clear of the surface beingcleained.' 'hen the verticalv 4distance between lsaid horizontal planes is greatest, the nozzle will engage the surface being cleaned and in vvsuch, case Will 'elevate the brush operatingrollers troinsuch sur-v face. so that the device will alone operate as a pneumatic cleaner. The device is desirl ablv. made convertible troni one kindof a cleaner to another bv affording two alternative vertical positions for the nozzle upon the casing wliu'li carries it and the brush opei-atingA rollers`v the` nozzle in one such position supporting the brush operatingr rollers Vout of contact with the surface being` cleaned and in'the other position beiner supported out ot' contact with su'ch surface by the brush operating rollers. l

l. will explain my invention more fully by reference to .the accompanying drawing which shows the preferred embodiment thereof and in \\'hich--- l y Figure 1 is a longitudinal sectional View of the preferred form of the invention; Fig. Q is a front view` partly inseotion; Fig. 3

aside view ot the front portion illustrating the machine as a pneumatic cleaner; and Fig. 4 is a side view of the front portion illust-rating the machine as a sweeper.

Like parts are indicated by similar characters of reference throughout the different f igures.- i Y..

First describingthe portions ot' .the drawings that reveal oneconst'ruction of pneumatic cleaner, I have provided a casing whichv has a partition t that 'divides the interior of the casing into two compartments 2, 3. An air suction pump,preferablyin the ."'form Yof a number of bellowsl orpnjeumatics 4, iS located in the upper compartment 2,

` actuating arms 5 projectingrearwardlyfrom the tops of the bellows. Pitnien 6 are linked to the arnis and have eccentric connection with the rollers or wheels `7 that engage the surface being cleaned whereby the bellows are'operated to pump air as the cleaner is moved back and forth. The wheels or rollers 7 are journaled in inountings `S .depending t'roin the partition t which is cut away to allow the pitmen to `work and to'attord free passage for air within the compartment Q as thc bellows contract. and expandtherein`r thereby perniiitting these bellows freely to operate. A tiap valve tl is provided for the air passage that occurs in the bottom of each bellows7 such valve opening` when itsv bellows eapands to permit the passage of air 1ino the bellows interior from the compart' niniiicates with willi rearwardly extending lingers 23, while below the pins Q4, the device is adapted to pivotally mounted at i9 and joined by links Q4 near the front of thev machine. yThe fasdust collector being within the space"3, the bag'being made of textile fabric that will intercept and collect the dust moving toward the bellows. The dust dist-barge end of the bag is surrounded b v a.-tliiii rubber plaie 1Q which is held in position against the wall of the'casing by thesnction nozzle 13, which latter is held ,in place by a swinging bail shaped clamp 14 which engages the forwardly projecting lower ends ot springs 15 whose upper ends are mounted upon the front face of the nozzle, these springs being rearwardly curved near the bottoni edges to receive and hold the front side ot' the clamp l-l. 'lhe nozzle has a nozzle opening which is elongated transverseljof the line olI i-nmeinent 'of the sweeper and is nia'de narrow longitudinally of such line ol' travel. 'lhe nozzle passage ieriiiinates at itsv lower en d in its elongated nozzle opening, and at itsl upper end it. c0m the interior of the dust col removably received lecting bag.

The easing ol' the machine ir provided with a sub-compartinent 16 in which a rotary brush 1T is received` the periphery of this brush projectingr but a slight distance below its compartment, pro|wrl v to have. brushing contact with the surface being cleaned. when thc machine is adjusted to' act as a sweeper as indicated in Fig. 4. The dust gathered by the brush 1T is discharged therefrom into the dust pans 18,

:'20 with a lever 2l. pivoled at' 22, the. lever being grasped at its right hand en d .(ltig. 1) to open and shut the traps, the 'forward trap discharging at itsl Jiront; end and tbe rea:- trap dir-charging at its rear end.

The sides oll the nozzle lil are provided the sido wall vportions of the'emnpartinent 3 are provided with laterally projecting pins tening elements 14 and 15 are adapted to hold the nozzle in position with .therngeis Q3 either above or below and in engagement with the pins 2.4. flien the lingers 23 are operate only as a pneumatic` cleaner, this being the adjustment illustrated in Figs. 1, 2 and $3. "hen the lingers 23 are`above. the pins 24, the device is adapted to operate only as a sweeper` this being the adjustment illustrated in Fig. 1. The rollers which drive the brush 17 desirably includes a small rubber bound wheel ateach end of `and co-axial with the. brush and a larger rubber bound wheel QG operativelv engaging each wheel .25 and having traction engagement with the surface being cleaned when the adjustment Villustrated iii Fig. lobtains. wherebythe rotary brush 2o may then l."

turned as thel machine is pushed forwardtiv and pulled rearwardly. Where the machine t 4roller being carried by is not to be operated as a sweeper, but as a pneumatic cleaner, and is accordingly given the adjustment illustrated in Figs. 1, 2 and 3, the nozzle 13 and wheels T cooperate to vsupport the machine to hold the wheels .ti

stitut'ed it pneumatic cleaner when the liorizoiital planesincluding the bottoni face. of the nozzle and the axisl et' the wheels Q6 are farthest apart and that the machine is constituted a sweeper when the space betweeii these. planes is reduced.

\Vliile I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of,.'construction shown aschanges may readily be made. without but Having thus descril'ied my invention l claim as new and desire to secureby Letters Patent. the followingzv 1. In a cleaner, the combination with a suction producing device; "of a suction noz zle for operation upon the surface to be cleaned; a casing with whose interior the nozzle and suction producing device communicate; a roller support; in driving rela.- tion to the suction producing device, said roller support engaging the surface to be cleanedwhile the nozzle engages said surfaee'thereby to be driven .and then in turn operating to drive the suction producing device; a rotary brush; a'roller for rot-ating the brush, said bi'usli and its operating said casing; and means whereby one end of the casing may be supported by the brush operating roller to the exclusion of the nozzle or by the nozzle departing from the spirit ot the invention,

to the exclusion of the brush operating roller to constitute the machine a Sweeper or pneumatic cleaner.

' 2. In a cleaner the. coiiibination with a suction'producing device; of a. suction nozzle 'forcperation upon the surface to be cleaned; a casing with whose interior the nozzle and suction producing device. communicate: a roller support in driving relation to the suction producing device, said roller support engaging the surface to be cleaned while the nozzle engages said surface thereby to be driven and then in tuin operating to drive the suction producing device: a rotary brush; a roller for rotating the brush, said brush and its operating roller being carried by said casingpand means fo1'.vm'yi11g the height of the axis of to thc brush operating roller whereby the rotation of tho brush operating roher with l rlronnpr may he (-onstitu-cd eil-her a pneu-- rospbi-t (o thc bottom fm'v of tinl nozzle. matic plennvnor Imrely :1. weeper.
